If you block me, you can't read this comment. I am putting up a free standing comment about how I have been researching this topic before thus video was shown on tv and again since seeimg this discussion. Persons not Rick who can understand answers when they ask questions might want yo reply to my free standing comment. BTW I rarely block. It is a person all quirk bUT I never saw rhe sense of it. I just minimize and if not minimize step over. Hey it is Disqus so not every commenter agrees with me or likes me or writes exactly what would be most interesting for me.
